I Specification of Letters Patent.

Application filed January 2?,1914, Serial No. 814,783. Renewed September;i1 (),1915. Serial no. 50,108.

Total} whom it may 00mm Be. it known that we, ANNiBALE STEFANINI and Giusnrrn GRADEMGO, subjects of the Italian King, and residents, respectively, of Pisa and Turin, Italy, have invented certain new and useful Improvements in Inhalers, of which the following is a specification, V

The present invention relates to an inhaler in which a doubleatomizing of the sub stances is obtained by the rebounding of the liquid jet on the wall. of an adjustable funnel provided with a long tube.. v i The improvement consists in that the tube of the funnel, which latter rotatably rests on a fixed bolt, rests on a stirrup which pivots on a bolt and may be secured to the latter in such a manner that the tube may be adjusted in any inclined position on said stirrup, in order that the moisture of the atomized liquid in said tube may be varied at will. I

The advantage of "thenovel device consists in that, even without heating, and by means of only one tube, inhaling subStances of any degree of moisture, from a wetmist.

to a dry dust or powder may be obtained, according to the inclination of the adjustable tube.

The inhaler is shown in lateral view in the accompanying drawing.

It comprises a plurality of ato-mizing devices which, under the action of compressed air at 1-1- to 2 atmospheres, project the liquid jet against the wall of a balloon or funnel B having a long tube (about 30 to 35 centimeters long) which may be inclined at will by rotatably mounting the funnel B on a bolt A located below the joining parts of the funnel and the outlet R through which the water, having not become atomized, is discharged. With this object in view, the

' tube is maintained by means of a rotary wooden fork or stirrup C, which may be adjustably secured on its pivot D mounted on the frame.

l/Vhen rotating the fork C, the middle portion of same describes an are E F and the inclination of the tube varies accordingly.

In such a manner the position of all funnels or of some of same may be adjusted according to'the nature of the dry powder or mist to beproduced. Instead of a fork a horizontal rod may be utilized on which rest the various funnel tubes so that they may be arranged in any inclined position. The inclination of the tubes should not become lower than degrees when itlisdesired to; blow drypowder through tubes whlchare not too long. The length of the forksis such that inclinations from 40 to on an interposed glass plate shows more clearly the cited properties. When comparing theproducts from sixdiiferently inclined tubes it is found that the three first tubes, having an inclination of 7 between 20 and 35 degrees, provide a v1 mistformed of droplets of 24, 18 and 14 thousandths of a millimeter while the three tubes inclined from 40 to 60 degrees provide a dry powder composed of mineral grains of from 12, 8 and 1-3 thousandths of a milli meter. Furthermore therdry powder from the above apparatus is charged with electricity which remains long after the powder has left the apparatus. This property cannot be found when making use of, other systems. The apparatus renders possible to accumulate, in the water used for inhaling purposes, the natural radioactivity of said water or that'transmitted to the water in any way by the substances deposited in the recipients ofthe apparatus, because the apparatus is the only one in which the-water, which has not been pulverized, flows back to the recipients, and the active products directly exhale in the room 'without 'belng heated again and without flowing through long wooden or metal pipes. 7

"When the pressure of the atomizingjet is low, or when the tube 13' C isshort and slightly inclined with respect'to the direction of the jet, a wet mist is produced; but the latter may be dried by heating the p pe by means of an electric current flowing through a coil of high specific resistance such as nickelin, wrapped around the tube. In such conditions the temperature in the substances may flow from thetube may beraised to degrees Celsius,

owing to which the water (under normal pressure) cannot remain in a liquid state. Owing to such heating a dry powder is obtainedwhen using a tube of 50 centimeters, even when making use of an atomizer op. erated by hand, by means of a small rubber ball or the like. This process is more particularly advised when the above apparatus is used for dry inhalings for domestic use or in hospitals and the like.

Owing to the system, of electric heating in combination with the varying of inclination of the tube, a more or less hot, wet mist may be obtained which is very convenient for complaints of the nose and the wind pipe. The temperature and the degree of moisture of the mist may be varied at will by adjusting the strength of the electric hegting current and the inclination of the tu e.

Having now fully described our said invention, what we claim and desire to secure by Letters Patent, is:

1. In an inhaler, the combination with a tube having an enlarged portion at its lower end provided with a draining aperture provided with a spout, a framework, apivot on said framework adapted to engage said spout for supporting the lower end of said tube, and means carried by the framework for varying the angle of inclination of the tube.

2. An inhaler comprising a tube, an en larged portion at the lower end of said tube, and open at its end, a frame, a pivot secured on said frame for pivotally supporting said enlarged lower portion of said tube, a bolt on said frame, a stirrup pivotally mounted on said bolt and supporting said tube and means for securing said pivoted stirrup, in any inclined position on said bolt, according to the inclination to be given to said tube.

3. An inhaler comprising an inhaling tube, an enlarged portionat the lower end of said tube, an aperture at the end of said enlarged portion, a frame, apivot secured on said frame, for pivotally supporting said enlarged lower portion of said tube, a bolt secured on said frame, a stirrup pivotally mounted on said bolt and supporting said tube, means for adjusting said pivoted stirrup in any desired inclined position according to the inclination to be given to said tube, an inhaling solution receptacle, a connecting tube between said solution receptacle and the lower end of said tube, a nozzle opening in said enlarged portion of said tube and adjacent the opening of said connectingtube, for sucking said solution and atomizing same within said tube. V In testimony whereof we have hereunto set our hands.
